What I'm looking for

I’m focused on data-driven decision-making in product and marketing contexts, using analysis to deliver clear, actionable insights.

At LCTB Branding & Digital Agency, I designed and maintained data-driven systems for tracking sales, projects, clients, and financial performance. I also analyzed website performance and marketing KPIs using Google Analytics, contributing to improvements in conversion rates, traffic, lead generation, and sales outcomes.

At Outer Baja Expeditions, I designed and delivered a data-driven web platform integrating real-time weather forecasts and geographic data. I also defined business KPIs and built operational dashboards and automated workflows in Monday.com to track bookings, revenue, customer behavior, and efficiency.

In my TripleTen projects, I used Python and statistical testing to analyze operations and evaluate A/B tests, including cases where the data did not support a confident decision. I built interactive Tableau dashboards and shared recommendations grounded in the analysis.

I’ve also developed a churn prediction project using supervised machine learning and clustering, and conducted marketing cohort analysis to examine retention and purchasing behavior. My work brings together data analysis, business context, and clear visual storytelling.
